DESCRIPTION:Decorators are powerful\, magical syntax sugar\, offering a con
 venient way to wrap and enhance functions. But sometimes\, it's not clear 
 how to use a defined decorator.\n\nWhat arguments should we pass to a give
 n decorator? What functions does it target? Does it change the return type
  of the wrapped function? Have you ever faced these questions?\n\nIf prope
 r type hints are defined for decorators\, static type checkers like mypy a
 nd pyright IDEs will point out the errors in usage. Thus\, guiding you on 
 the right path by catching bugs earlier\, reducing unnecessary debugging a
 nd unexpected runtime behaviour.\n\nThis talk will step you through type d
 efinitions utilizing `typing.TypeVarTuple`\, `typing.Protocol`\, `typing.P
 aramSpec`\, `typing.Concatenate`\, `Type Parameter Syntax`\, and more\, al
 l of which are practical to implement and can make your project robust!
